IVORYG. NUFTYT, OF GAINESVILLE, ARKANsAs' CAR-COUPLING.

SPECIFICATION forming part of Letters liatent No. 761,537, dated May 31,1904.

Application filed March so, 1904.

To aZZ whom it may concern.-

Be it known that I, IVORY; G. NUTT, a citi zen of the United States,residing at Gainesville, in the county of Greene, State of Arkansas,have invented certain new and useful Im- I .provements in Car-Couplers;and Ido hereby in which the cars will be uncoupled should =durable andin which lost motionbetweenfl one of them leave the'track, so as toswing sidewise at an angle to the other.

A further object of the invention is to provide a construction whichwill be simple and the cars will be prevented. o

In the drawings forming a portion of this specification, and in'whichlike numerals of reference indicate similar parts in both views, Figure1 is a" vertical section taken longitudinally through the draw-heads oftwo cars embodying the present invention. Fig. 2 is a top plan View ofthe structure shown in Fig. 1.

Referring now to the drawings, there are shown two cars 5 and 6. To theunder side of the body of the car-5 are connected the hangers 7 whilesimilar hangers 8 are connected to the under side of the car 6. In thehangers 7' is slidably mounted a draw-bar 9,

the inner end of which rests against ahelical spring 10, which in turnrests against and is secured to a depending bracket 11 on the bottom ofthe'car, so that the draw-bar is held normally and yieldably at theforward limit of its movement. The draw-bar 9 has a head 12, whichprojects above the upper face of the bar and has a rear face 13, whichlies at an acute angle to the upper face of the bar, the front face ofthe draw-headbeing beveled, as shown at 14:. Upon the upper face of thedraw bar and spaced rearwardly from the Serial No. 200,778. (No model.)

face 18 of the draw-head is a transversely-extending vertical flange 15,which by engagement with the/bumper 16 on the car limits prises astraight stem having a head 18 projecting downwardly therefrom, the rearface 19 of the head lyingat an acute angle to the under face of thestem, while the front face of the head is beveled, as illustrated at 20.

The member 17 is hinged between theears 21 on the-upper face-of thedraw-bar 22,

which is slidably mounted in the hangers 8 at the bottom of the car 6,the length of the stem of the member 17 being such that when .saidmember is in horizontal position the head lies beyond the front end ofthe draw-bar 22.

At the front end of the draw-bar 22 and projecting upwardly from itsupper face are the laterally-spaced ears 23, between which the stem ofthe member-17 is received when in horizontalposition, and from the sidesof the stem project the arms 24, which engage behind the ears 23, sothat the strain on the member 17 is not entirely upon its pivot.

Against the rear end of the draw-bar 22 is disposed a helical spring 25,the opposite end of which rests against and is secured to a dependingbracket 26, said spring serving to hold the draw-bar normally andyieldably'at I the limit of its forward movement.

With the construction shown when the cars are to be coupled they arebrought together end to end, so that the beveled face 20 strikes theface 14:, and in moving thereover the member 17 is raised until thelower extremity of its head passes beyond the rear face 13, when themember 17 drops and engages the lower end of its head behind the upperend of the head 12, the arms 24 at the same time engaging behind thecars 23, so that the two cars are held securely together. It will benoted that when the members are engaged as described the members 17 maybe disengaged from behind the head 12 if moved bodily in a lateraldirection, but that so long as both cars remain on the track thismovement of the member 17 cannot occur nor a corresponding lateralmovement of the head 12, such as would have the same result; but,however, should either car leave the track lateral bodily movement ofthe corresponding member 12 or 17 would result, so that the cars would be 1m coupled and damage would result only to the car that jumped thetrack, as in its fall it would not pull the neXt car with it.

When the coupling members are engaged, the lower end of the head 18 liesbetween the head 12 and the flange 15, so that the head 1 is heldagainst movement away from the face 13, excepting to a very limiteddegree.

To uncouple the cars, it will be understood that it is only necessary toraise the members 17, and for this purpose a shaft 27 is mountedtransversely of the front of the car 6 and has cranks 28 at its ends bymeans of which the shaft may be rocked. At the central portion of theshaft 27 is an arm 29, which projects forwardly and upwardly and to thefree end of which is connected a chain 30, which is connected also tothe perforated lug 31 upon the member 17. With this arrangement it willbe understood that when the shaft 27 is rocked in one direction the arm29 will be swung upwardly to raise the member 17, and when the shaft ispermitted to swing in the opposite direction the member 17 will belowered to its normal position.

What is claimed is- 1. A car-coupler comprising a draw-bar having a headprojecting upwardly from its forward end and a transverse flange uponits upper face upon the rear of the head and form ing an open-endedpassage between it and the head, a second draw-bar having spaced earsupon the forward end portion of its upper face, a latch membercomprising a stem pivoted in the rear of said ears and adapted to engagethercbctween, said stem having laterally-projecting arms disposed toengage behind the ears and having a depending head at its forward endadapted to engage behind the first-named head in the passage between itand the flange.

2. In a car-coupler, the combination with a slidable draw-bar having ahead projecting upwardly therefrom and an u puun'dly-directed transverseflange in the rear of said head, of means for holding the draw-baryieldably at the forward limit of its movement, a bumper in the path ofrearward movement of the flange, a second draw-bar having spacedupwardly-directed cars at its forward end, a latch member pivoted to thesecond draw-bar in the rear of the ears and adapted to engagetherebetween, laterally-projecting arms upon the latch member disposedto engage behind the ears, a head for the latch member disposed toengage between the first-named head and the flange, and means connectedwith the latch member for swinging it out of engaging position.

In testimony whereof I afiix my signature in presence of two witnesses.
